All-words word sense disambiguation in Turkish
Akçakaya, Sinan (Işık Üniversitesi, 2019-09-06)Word sense disambiguation (WSD) is the identi cation of the meaning of words in context in a computational manner. The main subject of this study is to implement and compare the WSD results of various supervised classi ers ... -
AnlamVer: Semantic model evaluation dataset for Turkish - word similarity and relatedness
Ercan, Gökhan; Yıldız, Olcay Taner (Association for Computational Linguistics (ACL), 2018-08-26)In this paper, we present AnlamVer, which is a semantic model evaluation dataset for Turkish designed to evaluate word similarity and word relatedness tasks while discriminating those two relations from each other. Our ... -
Automatic propbank generation for Turkish
Ak, Koray; Yıldız, Olcay Taner (Incoma Ltd, 2019-09)Semantic role labeling (SRL) is an important task for understanding natural languages, where the objective is to analyse propositions expressed by the verb and to identify each word that bears a semantic role. It provides ... -

Aysu, Erdinç (Işık Üniversitesi, 2018-06-19)The subject of this study is storing the large datasets in accordance with Big Data ecosystem and to extract the summary sentences of a text in Turkish, apply the automatic text summarization process which is a subtopic ... -
Bilingual software requirements tracing using vector space model
Yıldız, Olcay Taner; Okutan, Ahmet; Solak, Ercan (SciTePress, 2014)In the software engineering world, creating and maintaining relationships between byproducts generated during the software lifecycle is crucial. A typical relation is the one that exists between an item in the requirements ... -
Budding trees
Yıldız, Olcay Taner; İrsoy, Ozan; Alpaydın, Ahmet İbrahim Ethem (IEEE Computer Soc, 2014-08-24)We propose a new decision tree model, named the budding tree, where a node can be both a leaf and an internal decision node. Each bud node starts as a leaf node, can then grow children, but then later on, if necessary, its ... -
Calculating the VC-dimension of decision trees
Yıldız, Olcay Taner; Aslan, Özlem; Alpaydın, Ahmet İbrahim Ethem (IEEE, 2009)We propose an exhaustive search algorithm that calculates the VC-dimension of univariate decision trees with binary features. The VC-dimension of the univariate decision tree with binary features depends on (i) the ... -
